Slightly more derogatory variant of the term nudger, meaning male homosexual. The 'tupney'(short for tuppence, or 'two pence') part of the phrase implies that the subject is not only a homosexual, but one whose professional sexual sevices can be purchased quite cheaply.
There he goes, off on the game again, selling his crack to all and sundry. I say, What an A-grade tupney nudger!
